FOLDING BOX.

To all whom it may concern Be it known that I, GRovnR G. VVELTER, acitizen of the United States, residing at Roswell, in the county ofChaves and State of New Mexico, have invented certain new and usefulImprovements in Folding Boxes, of which the following is aspecification,- reference being had therein to the accompanying drawing.

This invention relates to folding boxes which are so constructed thatthey may be. readily converted from a set up position to a foldedposition, and which will be securely held in the folded position. This'box forms a very compact mass when folded so that there are no partswhich are liable to be injured in shipment. When the box is in a set upposition the cover may be either shut down upon the box, folded downbehind the rear wall, or moved so that it will be held in an inclinedposition above the rear wall.-

This invention is illustrated in the accompanying drawings, wherein-Figure 1 is a perspective view of the box in a set up position with thecover raised. Fig. 2 is a perspective View of the box in a collapsedposition. Fig. 3 is a vertical sectional view along the line 33 in Fig.4. Fig.4 is a vertical section along the line 44 in Fig. 3. Fig. 5 is asection along the line 55 in Fig. 4. Fig. 6 is a sect-ion along the line6-6 in Fig. 5. Fig. 7 is a fragmentary sectional View through theforward edge of the box when in a collapsed position. Fig. 8 is afragmentary perspective View of the upper portion of one of the endwalls. Fig. 9 is a fragmentary perspective View of one corner of thefront wall. Fig. 10 is a fragmentary elevation of one of the lowercorners of the box. Fig. 11 is a perspective view of the plate shown inFig. 10. Fig. 12 is a fragmentary view showing a different type of coverhinge from that shown in the remaining figures. Fig. 13 is a fragmentaryperspective View showing the hinge illustrated in Fig. 12. i

Referring to the accompanying drawings it will be seen that thisinvention comprises a bottom 15 which carries the end strips 16 and thefront strip 17. Reinforcing, plates 18 and 19 are secured to the cornersof the box so that the front and end pieces will be braced thus makingthe box -stronger.-

The plates carry upwardly extending tongues forming pivot cars 20 forthe end walls 21, and the forward plates 18 are pro- Specification ofLetters Patent.

vided with tongues which extend from the lower portions of the pivotears 20, and are bent inwardly to form the pivot ears 22 with which thefront wall 23 is jivotally connected. The front wall has plates 24mounted upon its end edges and pivot pins 25 pass through each pivot ear22, and the plates 24 so that the front wall will be pivotally mounted.Spring catches 26 are secured to the front strip 17 and fit into socke'ts 27 when the box is in a set up position. A handle 28 is mounted ineach of the end walls 21 so that the box may be conveniently handledwhen in a set up position. The rear wall 29 is provided with plates 30which carry the pivot bolt 31 so that the rear wall may be pivotallymounted between the end strips 16. The upper portion of the rear wall isprovided with slots 32 and strips 33 are secured to the rear wall andhave their intermediate portions crimped to form bearings 34 whichextend into the slots 32. A cover 35 is also provided with slots 36 andwith strips 37 having their intermediate portions crimped to form pivotbearings 38 fitting into the slots 36. Links 39 have their endspivotally mounted in the bearings 34 and 38 so that the cover will bepivotally connected with the rear wall and permitted to have a pivotalmovement independent of its pivotal movement with the rear wall.

If desired, the form of binge shown in Figs. 12 and 13 maybe used. Inthis form the cover is provided with cut-out portions 40 in each cornerand with strips 41 which extend along the edges of the cover, each stripbeing provided with a slot 42. The rear wall is also provided with acut-out portion 43 in each corner in which a strip 44 is mounted. Thestrips 41 and 44 take the place of the strips 33 and 37, and areconnectedby a link 45 which is pivotally connected with 'the strip 44and slidably mounted in the slot 42.

1 Each side wall is provided with a pin 46 which fits into the slot 47formed in the strip 48 mounted upon the edge of the front wall 23.- The'head of the pin 46 fits into thesocket 49 so that the side walls will beheld in a raised position. The rear wall 29 carriesthe strips 50 whichare similar to the --one-shown in Fig. 9, and are provided with slots inwhich the pins 51 fit to assist in holding the end walls erect. In theform shown in Fig. 12, the rear wall carries the pins 52 and the endwalls carry the catches 53 which have their free end portions out asshown at 5A to guide the pins 52 in the proper place.

The cover 35 is provided with a longitudinally extending strip 55 whichfits with in the front wall 23 when the cover is closed and prevents thepins 46 and 51 from slipping out of the notches in the plates as and 50,as clearly shown in Fig. 4L. The cover is provided with longitudinallyextending slots 56 through which the locking tongues 57 pass so that thelocks 58 may be passed through the openings 59 thus securely fasteningthe box. It will be obvious that either lead seals may be used to lockthe ,box as shown in Fig. 4, or any desired type of lock may besubstituted such for instance as a suitable padlock. Plates 60 aremounted upon the portions of the cover through which the slots 56 areformed so that the cover will be protected from wear.

The end walls 21 are each provided with a plate 61 which has its centralportion formed into a pocket 62 having its central portion crimped toform a recess 63 in which the curved end 64 of the strips 26 fit whenthe boxis in a collapsed posit-ion.

When shipping this box, the box is folded as shown in Figs. 2, 5 and 6with the cover folded back of the rear wall and the cover and rear wallfolded into the box and rest upon the bottom 15, the cover 35 being ontop of the rear wall. The front wall is then folded down upon the coverand the end walls folded upon the front wall with the catches 26 passinginto the pockets 62 and held in place by their curved ends 64 fittinginto the recesses 63. It will thus be seen that, by an inspection ofFigs. 5 and 6, the different portions of the box fit together verycompactly so that there is no danger of any of the portions being brokenwhen the box is being shipped from one point to another.

When the box is in use the end walls are raised and the front wall thenraised so that the pins carried by the front wall fit into the slots 47.The cover'and rear wall are then raised so that the pins mounted in therear corners of the end wall will fit in the slots formed in the plates50, thus securely holding the box in a set up position. The cover canthen be raised and the hinged end lowered behind the rear wall so thatthe cover will stay in the raised position shown in Fig. 1, or the covermay be turned back of the rear wall to the position indicated by thedotted lines in Fig. 4. If desired, the cover may be closed as shown inFig. 4, with the strip 55 fitting within the front wall and with thetongues 57 passing through the slots 56 so that the securing means 58may be passed through the openings 59 thus securely locking the box.

From the foregoing description it will be readily seen that this box maybe very easily set up and will fold into a very compast mass so that itmay be shipped without danger of being broken in transit.

What is claimed is 1. A foldable box comprising a bottom, front rear andside walls, links pivotally mounted upon the sides of said rear wall andprojecting above the edge, a cover provided with cut-out portions,plates mounted in said cut-out portions and bent along the hinged edgeof said cover, said cover plates being provided with longitudinal slotsin the side port-ions, and pivot pins passing through said slots andthrough said links to pivotally and slidably mount said cover betweensaid links.

2. A box comprising a body portion, the rear wall of said body portionbeing provided with slots leading from its upper edge, plates secured tothe rear wall of said body portion and crimped intermediate their lengthto form pivot housings fitting into said slots, links pivotally mountedin said housing and extending beyond the rear wall of said body portion,a cover for said box provided with slots leading from its inner edge,and strips carried by said cover and crimped intermediate their lengthto form pivot housings fitting into said secondmentioned slots, saidlinks having their outer ends pivotally mounted in said second mentionedpivot housings.

3. A box comprising a body portion, strips carried by said body portionand bent to formpivot housings, a cover for said box, strips carried bysaid cover and bent to form pivot housings, and links pivotally mountedin the housings of said firstmentioned strip and extending beyond theupper edge of said body portion and having their free ends pivotallymounted in the housings of said second mentioned strips.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.
